Abstract

Proposed hydrometallurgical processing of sulfide ores may generate tailings that contain sizable amounts of elemental sulfur. The possible use of these waste tailings as a readily available source of low-cost raw materials in the preparation of sulfur concrete was studied by the U.S. Department of the Interior, Bureau of Mines. The study showed that the waste, with some pretreatment, could be combined with aggregate to yield a high-strength, corrosion- resistant sulfur concrete for use by the waste producer at its plant for floors, footings, pump bases, or retaining walls in areas where conventional concretes fail because of corrosion. Two process wastes were examined: the Duval Corp.'s clear process residue and tailings from the ferric chloride leaching of galena ore, which has been pilot-plant-tested by the Bureau of Mines.
